Question

water has maximum density at

Answer 1

Water has maximum density at 4°C.

Answer 2

Water had maximum density at 4° C temperature. The water is an unique compound which has its maximum density at its liquid state, that is the solid form of water (ice) has less density than that of water at 4°C. This is the only reason that the ice floats on water. This property is also known as Anomalous behavior of water.
